Overview
Altair SimLab
Altair SimLab is a multidisciplinary simulation environment designed to help you automate the setup of complex engineering analyses. Instead of manually creating meshes for every part, you can use feature-based modeling to automatically recognize CAD geometry like holes, fillets, and ribs. This allows you to move from raw CAD data to a functional simulation model in minutes rather than hours, ensuring your engineering cycles keep pace with rapid design changes.
You can perform various analyses including structural, thermal, and fluid dynamics within a single interface. The platform is particularly effective for mid-to-large scale manufacturing companies in the automotive, aerospace, and electronics sectors. By capturing and automating repetitive modeling tasks, you reduce human error and free up your engineering team to focus on interpreting results and optimizing product performance.
SimFlow
SimFlow is a powerful computational fluid dynamics (CFD) platform that brings the capabilities of OpenFOAM to a user-friendly graphical interface. You can handle complex engineering challenges including compressible and incompressible flows, heat transfer, and chemical reactions without writing code. It allows you to import geometry directly from CAD software, create high-quality meshes, and monitor simulations in real-time to ensure accuracy and efficiency.
Whether you are designing automotive components or optimizing HVAC systems, the platform provides the tools to visualize flow patterns and pressure distributions effectively. You can run simulations on your local machine or scale up to high-performance computing clusters for massive datasets. It is designed for engineering professionals and researchers who need the precision of open-source solvers combined with the speed of a modern, intuitive workflow.
